FLUSHING DEVICE FOR WATER-CLOSET FIXTURES.

SPECIFICATION forming part of Letters Patent 1'\To. 668,589, dated. February 19. 1901. Application filed May 24, 1900. vSerial No. 17,881. (No model vpertains to make and use the same.

My invention relates to improvements in devices for flushing water-closetixtures ;v and i it consists in the novel devices hereinafter described and claimed.

My invention will be understood by reference to the accompanying drawings, wherein the same parts are indicated by the same letters throughout the several views.

Figure l is a vertical sectionalview of the flushing-tank, parts being broken away and. showing the interior mechanism; and Fig. 2

is a perspective view, on a much smaller scale, of the device as used.

A represents a tank, preferably of metal and of any suitable or convenient shape. This tank is provided with an upper opening A0, screw-threaded at a0 and fitted with a screw-threaded disk or plug A2, which when in place renders the tank air-tight. opening is contracted or provided at the inner portion with a surrounding flange a. A cylinder B, having an annular exterior flange h at its upper end, fits within the upper opening in the tank and is supported in a pendent position in said tank by means of the ange b on the cylinder, which rests on the flange c2 on the top of the tank. The bottom of the cylinder B does not extend to the bottom of the tank; but a sufficient space is left for the operation of the valve, as hereinafter more fully described. The cylinder B has a central opening B0 in its bottom, and within this opening is fitted one end of a tu be B', the said tube extending upwardly in said cylinder in an axial line something more than halfway the length of said cylinder. concentric tube C, somewhat longer than the tube B', passes through the latter and has connected to its lower end a short and large tubular portion O0,into the lowerend of which is tted a hollow screw-plug C. A rubber or A smaller.

other suitable elastic gasket or washer O2 of annular form is fitted over the screw-.plug C' and by the latter compressed against the lower end of the tubular portion C0, and thus retained securely in position. The lower plug C' is provided with a Valve-seat c/ at its up- -per end, and a relief-valve D, having a depending stem D', which passes axially through said plug, is shaped to lit said seat, the lower vend of the stem being provided withl an enlargement DO, having a beveled end do. The stem D of the valve passes loosely through an opening @son the guide-frame O3, and the enlargement D0 on the lower end of the valvestem D' allows a sufficient amount of axial movement to the valve-stem D to displace the relief-valve D from its seat when the stem is elevated to the limit of its upward movement.

The bottom of the tank A is provided with an outlet-opening A3, having beveled sides, and the gasket O2 is centered over this opening, so as to fit accurately thereon, thus forming the main outlet-valve. i The outlet-opening A3 is surrounded by atubular connection A4, which is adapted to be connected with the fixture to be ushed. Across this tubular connection A4 is diainetrically mounted a shaft or spindle A5, upon which is fixed a short curved arm or finger A6. The shaft or spindle A5 is provided at one end, which extends outside of the tubular connection A4, witha crank or handle A7, by means of which the said shaft or spindle may be turned. Upon the crank or handle being turned upwardly the curved arm or finger A6 bears against the enlarged end of valve-spindle and,forcing the parts upwardly,flrst displaces the valve D from its seat and afterward upon continued upward pressure elevates the tube O and the gasket C with their connections.

E represents the supply-pipe, which enters the bottom of the tank A and extends into the upper portion thereof.

The cylinder B is provided with a n'umber of openings ho on the same circumference thereof near its upper end. B2 B2 represent a pair of'oppositely-disposed triangularcatches, which are so pivoted as to have a tendency to fall inwardly toward eachother. The said pivoted catches have each a project-ion or iinger b2 upon its inner face, and these are ar- IOO ranged to enter openings Ui b3 at opposite points in the tube B'.

The inner tube G is provided with concavities o0 for the engagement of said projections when the said tube is elevated.

H represents ahollow float which is mounted over the tubes B and C, and b'L b4 represent a pair of divergent arms on the catches B4 B4, arranged to be struck by the said float and pressed outwardly when the latter falls, releasing the projections on the catches and allowing the tube O and the gasket carried thereby to fall and stop the outflow of water from the tank. This will not occur until the level of the water in the cylinder has fallen considerably, and the water may fiow out of the said cylinder only through the waste-cock B2, provided with a turning plug o8 for regulating the rapidity of discharge of the water from the said cylinder. Upon the tank refilling water enters the cylinder through the submerged waste-cock B8, as well as through the openings bo, and causes the float to rise, which allows the catches B2 B2 to resume their operative positions.

The operation of the device is as follows: \Vater is supplied continuously to the tank A through the pipe E, and the cylinder B is supplied from the tank through the openings bf and also through the `waste-cock B8. The level of the water in the cylinder falls as the level of the water in the tankfalls, though not nearly so fast, inasmuch as the water can escape from the cylinder only through the waste-cock BS after the water in the tank has fallen below the openings o0 in the cylinder. The float H in the cylinder rises and falls with the water in the latter. In order to flush the fixture X, the crank-arm Ais raised, causing the arm or finger A to engage the end do of the projection DO on the valve-stein D'. This first elevates the valve D from its seat c,thus relieving the pressure in the tank, and then raises the tube C and its connections C0 C' and the gasket or main valve C2, displacing the latter from its seat in the opening A3, allowing water to rush down through this opening and fiush the fixture. vWhen the tube C has thus been raised to its uppermost position, as indicated in dotted lines in Fig. l, the points b2 on the pivoted gravity-catches B2 engage the recesses e0 in said tube and hold the said tube and its connections aforesaid elevated. Upon the arm AT now being released it will fall to its normal pendent position, and the arm or finger A will also fall out of engagement with the end of the stem of the valve D, the latter falling by its own weight. \Vater will continue to run out of the tank through the opening A8 until the level in cylinder B falls sufcientlyto let the float drop to the position indicated in dotted lines in Fig. l, in which position said fioat engages the divergent arms b" on the gravitycatches B2 and, forcing them apart slightly, as also indicated in dotted lines, disengages the points Z22 of said catches from the tube C,

releasing the latter and causing it to fall and the gasket or main valve C2 to close the outlet-opening A2. The tank A and cylinderl B now refill.

By means of the plug b2 in the waste-cock BS the flush of the fixture maybe prolonged or shortened, as desi red.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
